Syntax Error JSON file read with AJAX - ajax

I am getting a syntax error for the square bracket '[' from my JSON file. Given below is the JSON.
[
{
"Product Name":"CPE 10281",
"Application":"Tyres",
"Weight":150,
"Cost to Produce":5000,
"Grade":"A",
"Cost to Sell":40000,
"Strength":100
},
{
"Product Name":"CPE 10282",
"Application":"computers",
"Weight":250,
"Cost to Produce":4000,
"Grade":"H",
"Cost to Sell":25000,
"Strength":90
}
]
I am trying to use AJAX to read my JSON file.
$.ajax({
url: "dataProductJSON.json",
dataType: 'json',
mimeType: "application/json",
success: function (data) {
var item = [];
$.each(data, function (key, val) {
item.push('<li id="' + key + '">' + val + '</li>');
});
$('<ul/>', {
'class': 'interest-list',
html: item.join('')
}).appendTo('body');
},
});
I am running my html from Eclipse with Apache Geronimo as the server.
Please Help.

You are missing a { in the below line
success: function (data)
Make it
success: function (data) {
Edit
You are having parsing the data incorrectly , do it as below
$.ajax({
url: "test.html",
dataType: 'json',
mimeType: "application/json",
success: function (data) {
var item = [];
$.each(data, function (key, val){
$.each(val, function (innerKey, innerValue){
item.push('<li id="' + innerKey + '">' + innerValue + '</li>');
});
});
$('<ul/>', {
'class': 'interest-list',
html: item.join('')
}).appendTo('body');
},
});
You need to use 2 loop , one for the array and the other to loop through the object property
I tried things and it is working fine

passing a parameter in url ajax

I have this code, how can I pass a parameter to data.php (data.php?q=) so when user digits something I can filter
the data and retrieve just a subset of records?
var company;
$(document).ready(function() {
$('.select-ajax').multiselect({
maxHeight: 400,
buttonWidth: '100%',
includeSelectAllOption: true,
enableFiltering: true
});
$.ajax({
type: 'GET',
url: '/data.php',
dataType: 'json',
success: function(data) {
$.each(data, function (i, item) {
company = item.company;
$('.select-ajax').append('<option value="' + item.company + '">' + item.company + '</option>');
console.log(item)
});
$('.select-ajax').multiselect('rebuild');
},
error: function() {
alert('error loading items');
}
});
$('.select-ajax').trigger( 'change' );
});
</script>```

Ajax - Parse oData Response

I have an ajax call that gets data from a REST api.
$.ajax({
url: "http://localhost:52139/odata/WEB_V_CIVIC_ADDRESS",
data: { enteredText: "'" + $('#addressTextField').val() + "'" },
type: "GET",
dataType: 'json',
ContentType: "application/json",
success: function (data) {
alert(JSON.stringify(data));
response($.map(data.accountaddressList, function (item) {
return {
item: item.civicaddress,
value: item.accountNumber,
label: item.civicaddress
}
}));
},
error: function (data, xml, errorThrown) {
alert('Error loading address list: ' + errorThrown);
}
});
The odata returned from that call looks like:
{
"#odata.context":"http://localhost:52139/odata/$metadata#WEB_V_CIVIC_ADDRESS/AValues.Classes.Entities.AccountAddress","value":[
{
"#odata.type":"#AValues.Classes.Entities.AccountAddress","accountNumber":88887,"rowNumber":0,"civicaddress":"123 Fake St"
},{
"#odata.type":"#AValues.Classes.Entities.AccountAddress","accountNumber":88888,"rowNumber":0,"civicaddress":"321 Faker St"
}
]
}
So the current code throws an 'Undefined' error on the line: response($.map(data.accountaddressList, function (item) {
How do I map the 'civicaddress' and 'accountNumber' from each value in the odata response to 'item'?
Thanks.
I got it, needed to change it to response($.map(data.value, function (item)

Simple jQuery / Ajax error

I have this code:
var custID = 1;
$.ajax({
url: 'php/viewCustomer.php',
type: 'GET',
data: '{custID: ' + custID + '}',
dataType: 'json',
cache: false,
beforeSend: function () {
$('#display').append('<div id="loader"> Lodaing ... </div>');
},
complete: function () {
$('#loader').remove();
},
success: function (data) {
//do something
},
error: function () {
alert('could not process');
}
});
there is an error and alerts the error message could not process, so I tried to debug it like this:
var custID = 1;
$.ajax({
url: 'php/viewCustomer.php',
type: 'GET',
data: '{custID: ' + custID + '}',
dataType: 'json',
cache: false,
beforeSend: function () {
$('#display').append('<div id="loader"> Lodaing ... </div>');
},
complete: function () {
$('#loader').remove();
},
success: function (data) {
//do something
},
error: function (jqXHR) {
alert('Error: ' + jqXHR.status + jqXHR.statusText);
}
});
which outputs:
200 OK
so if it is ok, why on earth is it executing the error: function. Confused, please help.
Your data string is incorrectly formatted, if you are intending it to be a JSON object. There was a previous question about this: Jquery passing data to ajax function
Instead, try:
data: JSON.stringify({custID: custID}),
The format is (key):(variable). My previous answer have placed quotes around the variable, which is not necessary.

ajax jquery pass null value

I get null values in the controller when I process the request using jquery ajax
Controller
[HttpPost]
public ActionResult UpdateAnswers(string answers, string question, string controlid, int eventid)
{
var replacetext=string.Empty;
if (answers.Length>0)
replacetext = answers.Replace("\n", ",");
_service.UpdateAnswers(eventid, replacetext, controlid);
return PartialView("CustomizedQuestions");
}
Jquery - Ajax Code
var test = "{ answers: '" + $("#answerlist").val() + "', question: '" + title + "', controlid: '" + controlid + "', eventid: '" + eventid + "' }";
$.ajax({
url: '#Url.Action("UpdateAnswers")',
type: 'POST',
dataType: 'html',
contentType: 'application/html; charset=utf-8',
context: $(this),
// data: "{ answers: '"+$("#answerlist").val()+"' ,question: '"+ title +"', controlid:'"+ controlid +"',eventid:'"+ eventid+"'}",
data: JSON.stringify(test),
success: function (result) {
$(this).dialog("close");
},
error: function () {
//xhr, ajaxOptions, thrownError
alert('there was a problem saving the new answers, please try again');
}
});
Your contentType is wrong. Why did you set it to application/html when you pass JSON? Try like this:
var test = { answers: $('#answerlist').val(), question: title, controlid: controlid, eventid: eventid };
$.ajax({
url: '#Url.Action("UpdateAnswers")',
type: 'POST',
dataType: 'html',
contentType: 'application/json; charset=utf-8',
context: $(this),
data: JSON.stringify(test),
success: function (result) {
$(this).dialog("close");
},
error: function () {
//xhr, ajaxOptions, thrownError
alert('there was a problem saving the new answers, please try again');
}
});
or using application/x-www-form-urlencoded which is the default:
var test = { answers: $('#answerlist').val(), question: title, controlid: controlid, eventid: eventid };
$.ajax({
url: '#Url.Action("UpdateAnswers")',
type: 'POST',
dataType: 'html',
context: $(this),
data: test,
success: function (result) {
$(this).dialog('close');
},
error: function () {
//xhr, ajaxOptions, thrownError
alert('there was a problem saving the new answers, please try again');
}
});

Ajax Json multiple parameters

This code below sitting on a ASP.Net application on the Site.Mater....
I need to pass another two parameters from the default.aspx page, one asp:label and one asp:textbox
What is the easiest way to do that?
Thanks
<script type="text/javascript">
$(function () {
$(".tb").autocomplete({
source: function (request, response) {
$.ajax({
url: "TestWebService.asmx/FetchList",
data: "{ 'testName': '" + request.term + "'}",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
dataFilter: function (data) { return data; },
success: function (data) {
response($.map(data.d, function (item) {
return {
value: item.Name
}
}))
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}
});
},
minLength: 2
});
});
In your jQuery autocomplete, You need to change your data parameter to this:
data: "{ 'testName': '" + request.term + "' ,lbl: '" + $(".lblClass").text() + "' ,txt: '" + $(".txtClass").val() + "'}"
And then change your service method like this:
[WebMethod]
public List<string> FetchList(string testName, string lbl, string txt)
{
//...
}
Note:
.lblClass and .txtClass are classes for ASP:Lable and ASP:TextBox respectively.
